반응 단계
A mixture of 1H-benzimidazol-2-ylacetonitrile (13 g), methyl 4-oxotetrahydro-2H-thiopyran-3-carboxylate (15.3 g), and ammonium acetate (33 g) was heated and stirred at 140° C. for 1 hour. The reaction mixture was cooled to room temperature, water and acetonitrile were added, and the resulting precipitate was collected by filtration and dried under reduced pressure to obtain 12-oxo-3,4,6,12-tetrahydro-1H-thiopyrano[4′,3′:4,5]pyrido[1,2-a]benzimidazole-5-carbonitrile (16 g).
